Summary

Southern and Central California are set to receive substantial rainfall starting late on October 20, marking the first significant storm of the season after a period of high temperatures. The National Weather Service forecasts rain, snow in the Sierra Nevadas, and dangerous surf along the coasts.
Impacts are expected to be strongest south of the Central Valley. While Northern California may remain dry, the Sierra Nevadas could see light showers and thunderstorms, with 3 to 6 inches of snow above 8,000 feet. Central Valley areas like Fresno and Merced might receive under an inch of rain, with Shaver Lake seeing more.
Coastal areas from the Central Coast to Los Angeles anticipate half an inch to an inch and a half of rain from October 21. Hazardous conditions include potential flooding and debris flow in areas with recent burn scars, and high surf with dangerous rip currents along Ventura and Los Angeles County coasts. Southern California counties have a 30-50% chance of rain, with cooler temperatures being a primary impact.
